Panning for DNA - A regularly performed isolation of DNA from calf thymus gland conducted by our Explainer (docent) staff. This dramatic demonstration provides visitors with an opportunity to appreciate the mass of DNA in cells and gives them a first-hand opportunity with the DNA.

Map Analogy - a graphical presentation of the size, scale, and location of the human genome in comparison to the Earth.

DNA technology gives us access to new information and allows for direct manipulation of an organism's genome. Mapping an organism's genetic information provides a powerful key to the organism.

Cracking the Code - an interactive computer-based presentation of the development of the automated DNA sequencer and molecular view of a sequencing experiment and subsequent analysis

Dancing DNA - observation and manipulation of real individual DNA strands moving in an electric field and viewed through a microscope, showing the basis by which DNA segments of different lengths are separated in a electrophoretic gel.

DNA Race - a computer program modeling the movement of DNA through a gel. Here visitors may rapidly manipulate simulated DNA in a simulated gel.

All living things are genetically related (we share 97% of our genes with mice). Differences between species are caused by mutations or variations in the genome. Studying other organisms gives us understanding about ourselves

DNA and the Developing Embryo - a microscopic display of living zebrafish embryos. These particular fish rapidly develop from eggs to fry in only 48 hrs. Their eggs are water-clear. This makes the display of these remarkable changes visible and dramatic to watch.

Musical Mutants - a computer-based whimiscal and musical exploration of the effects of various kinds of mutations on protein sequences in different organisms

Tank of Mutants - a display of many of the variations found in one particular species of fish. Genetic variations are the touchstone of genetists for insight into the development of an organism. Here we display a small subset of the variations or mutations found in zebrafish.

Mutant Flies - a display of various morphological and behavioral mutations in fruit flies (fruit flies have been important in studies of genetics, partly because of the similarity of fruit fly genes and human genes, and because of their rapid reproduction)

Prehistoric Insects - an interactive display of insects and other organism trapped in ancient amber. None of the observed species are currently alive but all lived some 25 to 40 million years ago.

Mutant Detector - a somewhat silly exhibit based on the notion that we all carry a number of mutations within us.

Sexual reproduction mixes up genes and makes us unique (it takes two to make three). Traits are passed from one generation to another

Sickling Cells - observation of physical change in human blood cells containing sickling hemoglobin, from someone with sickle-cell anemia, through modification of the oxygen concentration; the exhibit shows the molecular structure of hemoglobin and how the HbS polymerizes due to a changed amino acid on the surface of the beta-S chain

Sickle Cell Counselor - an interactive multimedia exhibit which lets visitors play the role of a genetic counselor in making recommendations and providing guidance to prospective parents. The computer program provides a sophisticated learning environment and presents the genetic science behind Sickle Cell disease and possible options.

Genetic Characteristics - a computer-based self-examination of various inherited characteristics emphasizing the uniqueness of the individual

Father's Nose - a simple look at inheritance using mirrors and clear areas in a panel. Two people can sit across from one another and gaze at each other and see a composite image of their own face and their partner's. The concept here is that genes for specific features are expressed discretely and not as a blend.

Egg Fertilization Demonstration - a regularly scheduled demonstration introducing the concepts of meiosis and mitosis through a display of the fertilization of sea urchin eggs, or other suitable preparation, under microscopic view.

Ethical considerations are integral to the human genome. Here we provide visitors with an snap shot genetic issues and the surrounding debate and ask them to participate via pen and paper and computer.

Talk Back Boards - Visitors will be given the opportunity to express their own views on the ethical issues raised by genetic research. At four separate tables various ethical dilemmas will be posed and visitors will be invited to respond with their opinions via 3 X 5 cards which Exploratorium staff will post at regular intervals.

Genes in the News - A broadly based collection of recent articles focused on genetic news. The short articles will come from newspapers and journals.
